The company offers a $30 JFK Tour Deluxe. According to its website, patrons get a tour of Lee Harvey Oswald's apartment, are driven along the route JFK's motorcade took on the day he was shot and watch footage from the day.

After seeing pictures of the bus, people quickly took to social media to express their disdain.

KXAS spoke to at least one person in Dallas who didn't have a problem with the bus.

Timothy Moon told KXAS, "I can see how people could take that the wrong way. Um, I think those people should probably just relax."

WFAA spoke with the Dallas Convention and Visitors Bureau which owns the "Big Things Happen Here" slogan. In a statement, the bureau said: "Although we appreciate [the owner of Dallas City Tours'] enthusiasm for the Dallas brand and his service to tourists, he has been notified that he is not authorized to use the trademarked logo/brand/slogan."

The outlet also spoke with the owner of the company, who didn't want to speak on camera but said the bus didn't turn out quite how he'd intended.

Marie Saavedra for WFAA says, "He tells us that the slogan 'Big Things Happen Here' was supposed to be on the other side of the bus, not near Kennedy's head. He regrets how it looks."
